Observed massive neutron stars may contain heavier baryons such as $\Delta$ isobars and hyperons in their interiors. In the presence of $\Delta$ isobars, the neutrino emitting nucleonic Urca processes can be accompanied by $\Delta$-direct-Urca processes involving nucleons and hyperons. Over the past three decades, sign...
